The specific heat capacity of aluminum is .89 J/y degrees C. How much heat is required to change the temp of 1500g aluminum pan from 25 degrees C to 100 degrees C?
q = mass Al x specific heat Al x delta T.
I got 100125 is that correct?
To calculate the amount of heat required to change the temperature of a substance, you can use the formula:
Q = m * c * ΔT
Where:
Q is the heat energy (in joules)
m is the mass of the substance (in grams)
c is the specific heat capacity of the substance (in joules per gram per degree Celsius)
ΔT is the change in temperature (in degrees Celsius)
In this case, you have the following values:
m = 1500 g
c = 0.89 J/g°C
ΔT = (100°C - 25°C)
First, let's calculate ΔT:
ΔT = 100°C - 25°C = 75°C
Now we can substitute the values into the formula and calculate the heat (Q):
Q = (1500 g) * (0.89 J/g°C) * (75°C)
Q ≈ 100,125 J
Therefore, approximately 100,125 joules of heat energy would be required to change the temperature of the aluminum pan from 25°C to 100°C.
